The number one thing to do as he grows: allow his curiosity to flourish, even if it means letting him hurt himself a bit. Some learn better through words. Some learn better through visuals. This is mostly rote memory stuff, and it's crap. Everyone learns better through experience, and experience builds both memory and extrapolation. He might only be six months old, but he's already got a keen brain for gathering data and deducing outcomes. It's intrinsic to human nature, and it's commonplace to stifle it with too many boundaries. Don't. I'm not saying you should throw caution to the wind, but don't be as protective as the societal norm says you should be.

Allowed to be curious, he'll get critical thinking skills, passion for exploring the unknown and street smarts out of the deal. He'll immediately be better at anything he sets his mind on than those who have been forced into learning only through written and verbal means.
